The-inVenti0l} relates to suspension or connectinggdevies j or insuiators, particularly those :ofthe He wlett tyfpe,

Ihe priinary objet of the invention, gen- 6 orally;st&ted,is q.prvide a. suspension device for 'meoiinialiyonnecting high ten: sinsnspen siori ins uiators together in se r t I SQ?FS W m In the Hewl ettty e pf, insuiator .two arcua'te 10 hois a re forme in the body in such manner that they interiinir,5vithin the insulating materiaiwith :apsubstantal wali 'separating them and eiect-uallydnsulating themet-allie connetingflevies received by and extending w ithin and through the arcuate holes.

"ari ous devics have been provided :f.or effc'cting connectionand in some instances use hasbeen inadogof U-shaped or .shaped ]ink or sypke ,membeis engaging through the holes or passages in the insulators and connected at theirendsby boits or thelikebut the welLknownstrutures possess many disadvantages ,ioremost aning which is difficuity in assemb ling. A

Tige object of the invention, more specificaliy stated;is to pro vide insulator suspension ,means inoludi ng 1embers o f curved form adapted to be;insertad or threaded through the arcuate hoies in the insulat0rs, and .oonnectinguneansadapted to be engaged .upon the..ends thereof without the employment of bolts, pins or other securing elements which are diflicult to apply, the conneCting me mhe1having, moreover, auX- iiiary hOiding .means associated therewith whereby .subsequent accidental disconnectien or djsplacernent of the parts will be prevanted while at the same time disconnection for the purpose of making repairs or repiacements may \be readiiy accomplished wheneverthe occasion arises. V

An important object is the provision of suspension xneris;of this character which will posSess1consfliderpble fiexibility so that when :i-stringiof -conneoted insulators-is sus pended: the various unitsmay automaticaiiy accommodate themselves to the line of tension. and:.be eonsequentlygarranged in coaXial relation, the flexibility bing, however, limited tosuch an extent that a string of insultors'may be reed from their crate and hoisted int0 place by conncction 'of a hoist line withi an intermediate portion 'of the string, withont the resuitant bowin of th string being suificient to cause the successive nuits to come into contact.

A further object of the invention is to proride connetion or suspension means of this character in which the various eIements are -i"ree from Sharp corners or projections so that the formation of coroi1a points Will be avoided.

Stilianother object of the invention. is to prox-ide connecting or suspensionmas of titis charactcr involving or embodying duplicata parts which are'consequently capable of rerersai and interchangability so that there wili be no rights or lofts or other complications to cause confusion and delav in assen.biing. 4

A 'urther object of the invention is th provision of an improved nd simplified construction of such insulator cohnectorS b rneans of ivhieh ii1creased streixgth, durabiiity and utility may. be obtained in addition to the convenience of operation.

To these and other ends the invention comprises the various elements and combii=ations of lements to b.hereinafter more fully described and set forth in the claims herennto appended.

In the drawings:

Figure 1 is a vertica l section through,a string of insuiatoxs coiinected by my suspension means, certain parts of the Suspension 2neans or devices being shown in section, and other parts in elevzition.

Figure 2 is a detai1 section iliustrating the auxiiiary holding means more clearly and in grenier detaii.

Throughout the specification and drawings like parts are designated by like reference characters.

Referring to the drawings in detail, I have illustrated a string 01 insulators 1 Of the Hewiett type and each insulator is formed with interli1iking arcuate holes or passages 2 and 3, the former curving dow1r wurdly and the latter curving u'pwardly. 'ihese passages interiink within the body of the insuiator and arespaced apart or separated by a substatial portion 4 of the insidzitor. V

In carrying out the invention I provide connecting or suspension means including a pair of curved yoke or link members 5 which jecting beyond the end of the crate. After the string is hooked in place the crate is re moved. However, with the units connected by the means forming the subject-matter of this invention, the erate may be initially removed and in this instance the hoisting device may be Connected with an intermediate portion of the string. WVhile the connecting or suspension devices possess considerable fiexibility, as above pointed out, it Wiil be scen that the flexibihty is limited so that in case an assembled string is hoisted by engagement of a hoist line or the like with an intermediate portion, the rasuitant bowing of the string cannot bring the successive insulator units into contact. This feature is important inasmuch as such con tact of the units during hoisting would in all probability prove disastrous as the dan ger of breakage would be considerable.

Connecting and suspension means constructed in accordance with the prescnt invention will be extremely easy to apply on account of the absence of bolts, pins or other simiiar securing elements which are diificult to handle and insert properly in position, and furthermore, for the reason that the connectors and yokes are all interchangeable and reversible. Initial securing is eflected merely by interengagement of the yokes and connectera themselves and permanent securing is accomplished simply by sliding and springing the auxiliary fastcncr in place. All the parts are of such construction as to possess grcat strength and durability.

Having now described my invention, what I daim is:

1. Means for connecting insulators having curvcd insulating passages comprising a pair of similar cnrved yoke members adapted for insertion through the interlinking passages of successive insulators and terminating in heads adjacent constricted neck portions, and connecting members apertured for the reception of said neck portions and ha ving retaining surfaces co-acting with said heads, said connecting mcmbers ineiuding intermediate transverse portions spaced from the ends thereof to provide apertures for securing means.

2. Means for connecting insulators having curved insulating passages comprising a pair of similar curved yoke members adapted for insertion through the interlinking passages of successive insulators and terminating in heads adjacent constricted neck portions, connecting members apertured for the reception of said neck portions and having retaining surfaces coacting with said heads, said connecting members including intermediate transverse portions, in combination with a securing member adapted to extend through the connectors in embracing relatien to the intermediate portions thereof and coacting with said heads to prevent disengagement of the connecting members from the yoke members.

3. Means for connecting insulators having curved insulating passages comprising a pair of similar curved yoke members adapted for insertion through the interlinking passages of successive insulators and terminating in heads adjacent constricted neck portions, connecting members apertured for the recep tion of said neck portions and having retaining surfaces coacting with said heads, said eonnecting members including intermediate transverse portions, in combination with a securing member adapted to extend through the connectors in embracing relation to the intermediate portions thereof and coacting with said heads to prevent disengagement et the connecting members from the yoke members, said securing member having a iateral portion engaging outwardly of one intermediate portion for preventing withdrawal.

4. Means for connecting insulators having suspension members projecting therefrom and terminating in heads adjacent constricted neck portions. comprising connterpart connecting members apcrtured for the reception of said neck portions and having rctaining seats coacting with said heads. in combination with an auxiiiary rctaining element exiending through both connecting membcrs in engagement with said heads, said members including intermediate welo portions, and said auxiliary element emhracing said web portions.

In testimony whereof I affix my signature.
